the lack of effort the Ownership has ... the past Years since Henry retired
Not sure this is fair. They obviously have not done enough last year and for this upcoming season, but we were really good during Marsch's tenure here.
I know a lot of people will disagree with this, but I view RB's firing of Petke as an example that they cared, at least in 2015, about winning. Why fire a coach that the majority of fans adored? Why piss off so many people? One argument would be, that they don't care about the fans. I think it's more likely, they didn't think Petke was any good and brought in someone that they, correctly, thought was. They felt it was the right decision for winning, so they took the unpopular route.
All that said, ownership has gone AWOL this offseason.
